A medical device for the treatment of a sinus opening includes a handle, a grooming sheath, a rail, a guide wire, a balloon catheter and a balloon catheter movement mechanism. The handle has a proximal end, a distal end and a longitudinal axis along the length of the handle. The grooming sheath has a distal end and a proximal end with the proximal end of the grooming sheath being attached to the distal end of the handle. The rail has a distal end and a proximal end and disposed partially within the grooming sheath to define an annular lumen is between the rail and the grooming sheath. The guide wire operatively extends from the distal end of the rail and the balloon catheter is disposed at least partially in the handle and annular lumen. The balloon catheter movement mechanism operatively disposed on the handle and configured for advancement and retraction of the balloon catheter through both the handle and the annular lumen and along both the rail and guide wire by user operation of the balloon catheter movement mechanism. A method for treating a sinus opening includes inserting a medical device for the treatment of a sinus opening partially into a patient's anatomy and then positioning a guide wire operatively extending from a rail of a medical device into a sinus opening of the patient. The method further includes advancing a balloon catheter from an annular lumen of the medical device and along both the rail of the medical device and the guide wire. The method also includes treating the sinus opening via inflation of the balloon catheter. In the method, the annular lumen is between the rail and a grooming sheath of the medical device and the advancing is accomplished via user operation of a balloon catheter movement mechanism of the medical device.
